By outrighting Tim Stauffer and Dustin Moseley on Friday, the Padres dropped two-fifths of their planned 2012 rotation from the 40-man roster. Both have opted for free agency, the Union-Tribune reports.

Stauffer had a 1.85 ERA in seven starts and 25 relief appearances for the Padres in 2010 and a 3.73 ERA in 31 starts in 2011, but he made just one appearance in 2012 before going down with an elbow injury. Season-ending surgery to repair his flexor tendon followed.

Moseley, likewise, made just one start this year. He underwent labrum surgery on his shoulder in April, and he probably won’t be ready for the start of 2013. The 3o-year-old made 20 starts for the Padres in 2011 and went 3-10 with a 3.30 ERA.

One imagines the Padres will try to re-sign Stauffer at a lesser salary than the $3.2 million he made this year. Edinson Volquez and Clayton Richard are their only veteran returning starters, and the team will surely listen to offers to both this winter. Andrew Cashner also figures to have a spot in the rotation if healthy, but the Padres will need to add depth, and pitchers might not be quite as eager to sign with the team now that the fences at Petco are coming in a bit.

Dustin Moseley made just one start before being placed on the 15-day disabled list earlier this month with what was originally termed as a right shoulder strain. Padres manager Bud Black told Bill Center of the San Diego Union-Tribune last week that an MRI on the shoulder showed “damage to the rotator cuff and changes to the labrum” and conceded that surgery was “a possibility.”

Moseley could opt to rehab the injury, but if the condition of his shoulder doesn’t improve, undergoing surgery a couple of months from now could delay his ability to be ready for the start of the 2013 season. With that in mind, Moseley told Dan Hayes of the North County Timestoday that surgery is probably his “only option” at this point.

It’s not clear how long Moseley would be sidelined if he ultimately goes under the knife, but it’s safe to say that the rest of his season could be in danger. Tim Stauffer is currently sidelined with a right elbow strain, so Anthony Bass and Joe Wieland will continue to hold down rotation spots for now.

Moseley, 30, posted a surprising 3.30 ERA and 64/36 K/BB ratio over 120 innings with the Padres last year before undergoing season-ending surgery on his left (non-throwing) shoulder.
